HEAT-GENERATING ALLOY WIRE FOR ELECTRIC WIRE HARDLY DEPOSITING ICE AND SNOW

摘要

PURPOSE:To effectively prevent that ice and snow adhere to a transmission line by providing an alloy wire wherein its heat-generating efficiency is high with a small current in the winter season and its heat-generating efficiency is low with a large current in the summer season. CONSTITUTION:A heat-generating alloy wire for an electric wire on which ice and snow are hard to deposit is provided with a core material 1 composed of a magnetically soft material, with a coating material 2 which covers the core material 1 and which is composed of an Fe-Ni-based alloy and with a corrosion-resistant layer 3 which covers the coating material 2 and which is composed of Zn, a Zn allay, Al or an Al alloy.
